+ Yep, the head lore is no longer needed to sell heads! (It was causing issues anyways...) It can be re-enabled or disabled in config.yml.
+ Possible exploit issues with /sellhead fixed
+ heads.yml has a new format (old values are transferred over)
+ New config option, gui-glass-color, which modifies the glass color in /hpc and /heads.
+ Some bug fixes

Any issues with this update let me know.~
